Looks like a shift from operational to general concepts (except a few that point at other things like https and doi). With much greater complexity everywhere, one would hope discussion isn't dominated by super basic stuff. But with greater specialization, such terms may simply represent lowest common denominator terminology that appears everywhere (like articles, prepositions, conjunctions, etc) rather than actual content. kyle On Tue, Feb 2, 2021 at 8:08 AM Eric Lease Morgan <[log in to unmask]> wrote: > ... > Both clouds include words like "library", "information", and "data".
